Program Outcome #1: Demonstrate core knowledge about established and evolving biomedical and clinical sciences and the application of this knowledge to patient care in their area of practice. 1) Find and paste the risk factors for the development of coronary artery disease. Please provide URL of site you used to answer this question. Increasing age Male sex (gender) Heredity (including Race) Tobacco High blood cholesterol High blood pressure Physical inactivity Obesity and overweight Diabetes mellitus http://www.americanheart.org/presenter.jhtml?identifier=4726 2) Find and paste a discussion of the pathophysiology for endemic goiter. Please provide URL of site you used to answer this question. The thyroid gland is controlled by thyrotropin (TSH), secreted from the pituitary gland, which, in turn, is influenced by the thyrotropin-releasing hormone (TRH) from the hypothalamus. TSH permits growth, cellular differentiation, and thyroid hormone production and secretion by the thyroid gland. Thyrotropin acts on TSH receptors located on the thyroid gland. Serum thyroid hormones levothyroxine and triiodothyronine feed back to the pituitary, regulating TSH production. Interference with this TRH-TSH thyroid hormone axis causes changes in the function and structure of the thyroid gland. Stimulation of the TSH receptors of the thyroid by TSH, TSH-receptor antibodies, or TSH receptor agonists, such as chorionic gonadotropin, may result in a diffuse goiter. When a small group of thyroid cells, inflammatory cells, or malignant cells metastatic to the thyroid is involved, a thyroid nodule may develop. A deficiency in thyroid hormone synthesis or intake leads to increased TSH production. Increased TSH causes increased cellularity and hyperplasia of the thyroid gland in an attempt to normalize thyroid hormone levels. If this process is sustained, a goiter is established. Causes of thyroid hormone deficiency include inborn errors of thyroid hormone synthesis, iodine deficiency, and goitrogens. Goiter may result from a number of TSH receptor agonists. TSH receptor stimulators include TSH receptor antibodies, pituitary resistance to thyroid hormone, adenomas of the hypothalamus or pituitary gland, and tumors producing human chorionic gonadotropin. http://www.emedicine.com/med/topic916.htm 3) A normally healthy, 25 year old white male who recently developed an infection with influenza A2, develops the following: Hemoptysis Nausea and vomiting Chest pain Arthralgias Hematuria Tachypnea Inspiratory crackles over lung bases Based on the above signs and symptoms, what is the patient’s most likely diagnosis? Please provide URL of site you used to answer this question. Goodpasture’s disease URL: XXX 4) Assume that you wanted to investigate for the presence of a bleeding disorder (congenital OR acquired) in a patient. The following tests (with results) were obtained. Based on the labs below, choose the likely bleeding disorder from those listed. Hematocrit (male) Hemoglobin (male) Platelets aPTT INR A) B) C) D) 45% 16 g/dL 250 K cells/mm3 60 Sec 1.0 Hemophilia A DIC ITP Vitamin K Deficiency Prothrombin time (PT) If the PT is over 1.5 the mean of the reference interval, suspect single or multiple deficiencies of the "extrinsic" and "common" factors prothrombin, fibrinogen, V, VII, or X. The factor with the greatest impact on the PT is VII. Partial thromboplastin time (PTT) If the PTT is over 1.5 the mean of the reference interval, suspect single or multiple deficiencies of the "intrinsic" and "common" factors prothrombin, fibrinogen, V, VIII, IX, X, or XI. Deficiencies of the "contact" factors XII, Fletcher (prekallikrein), or Fitzgerald (high molecular weight kininogen, HMWK) also prolong the PTT but are not associated with bleeding. Very prolonged PTT results (> 200 s) are due to heparin until proven otherwise. PT PTT Acquired Disorder Long Normal Liver disease or vitamin K deficiency Normal Long Acquired factor VIII inhibitor Long Long DIC, liver disease, Lupus anticoagulant (LA) Normal Normal Thrombocytopenia, qualitative platelet disorder Congenital Disorder Factor VII deficiency Factor VIII (Hemophilia A), IX, or XI deficiency Fibrinogen, prothrombin, factor V or X deficiency Mild factor deficiency, mild von Willebrand disease, factor XIII deficiency DIC is generalized activation of coagulation secondary to systemic conditions such as septicemia, carcinoma, and severe inflammation or pregnancy complications. The presence of high concentrations of D-dimer, often > 20,000 ng/ml, is the sine qua non criterion of DIC, as it reflects increased fibrin production and breakdown. In acute DIC, activation of the tissue factor (intrinsic) pathway results in a decrease in factors II, VII, IX and X, prolonging the PT and PTT. However, an increase in factor VIII production coupled with von Willebrand factor released from the endothelium may make the PTT less useful than the PT in laboratory diagnosis of DIC. The PT is also expected to be abnormal before the PTT because it is highly dependent on factor VII level, which has a very short half-life of 3-5 hours. Assay PT PTT Fibrinogen Quantitative D-dimer Complete blood count with platelet count Expected Results in DIC Usually prolonged (even before PTT becomes prolonged) Usually prolonged above upper limit of reference interval Low; but may be normal or high due to acute phase reaction; sequential measurements are helpful Significantly above the limit of reference interval · Single most important assay to establish DIC · In compensated DIC, D-dimer may be the only abnormal test Anemia with schistocytes Low platelet count reflects significant consumption but count may be near normal due to marrow response ITP stands for idiopathic thrombocytopenic purpura. "Idiopathic" means that the cause is unknown. "Thrombocytopenic" means the blood doesn't have enough platelets. http://peir.path.uab.edu/coag/article_222.shtml#a 5) The patient in the following photograph developed a painful, vesicular, unilateral eruption on his chest (in the distribution shown below) a few weeks after being placed on a corticosteroid regimen for the treatment of his asthma.

This rate applies to PAs practicing in all care settings including hospitals (inpatient, outpatient, and emergency departments), nursing facilities, homes, offices, and clinics; it also applies to first assisting at surgery. All visits should be billed at the full physician rate; the PA's NPI number (or PIN) will signal the Medicare carrier to implement the 15 percent discount. What number should appear in the blank above?85 http://www.aapa.org/gandp/3rdparty.html Program Outcome #4: Use investigatory and analytic thinking approach to clinical situations This evidence supporting the acquisition of this outcome is found in the answer/s to the questions associated with outcome #6 below. 10) If the entry hemo* is entered into the search box of a database that recognizes truncation, a search will be conducted for all of the following except A) hemorrhage B) hemorrhoid C) hematuria D) hemostasis 11) Words such as "AND", "OR", and "NOT" are referred to as A) descriptors B) operators C) indicators D) regulators Program Outcome #5 - Display interpersonal and communication skills that result in effective information exchange with patients, their patients’ families, physicians, professional associates, and the health care system 12) Provide a brief, one paragraph interpretation of the answer to question question #2 above in a manner that would be understandable to a high school student with no medical background. Grader, please use your own judgment regarding whether or not the “translation” is 1) accurate and 2) appropriately worded for a young, lay person. 13) Find and paste the types of information that should be included in the documentation of a history of present illness (HPI)? Please provide URL of site you used to answer this question. 1. Duration: How long has this condition lasted? Is it similar to a past problem? If so, what was done at that time? 2. Severity/Character: How bothersome is this problem? Does it interfere with your daily activities? Does it keep you up at night? Try to have them objectively rate the problem. If they are describing pain, ask them to rate it from 1 to 10 with 10 being the worse pain of their life, though first find out what that was so you know what they are using for comparison (e.g. childbirth, a broken limb, etc.). Furthermore, ask them to describe the symptom in terms with which they are already familiar. When describing pain, ask if it's like anything else that they've felt in the past. Knife-like? A sensation of pressure? A toothache? If it affects their activity level, determine to what degree this occurs. For example, if they complain of shortness of breath with walking, how many blocks can they walk? How does this compare with 6 months ago? 3. Location/Radiation: Is the symptom (e.g. pain) located in a specific place? Has this changed over time? If the symptom is not focal, does it radiate to a specific area of the body? 4. Have they tried any therapeutic maneuvers?: If so, what's made it better (or worse)? 5. Pace of illness: Is the problem getting better, worse, or staying the same? If it is changing, what has been the rate of change? 6. Are there any associated symptoms? Often times the patient notices other things that have popped up around the same time as the dominant problem. These tend to be related. 7. What do they think the problem is and/or what are they worried it might be? 8. Why today?: This is particularly relevant when a patient chooses to make mention of symptoms/complaints that appear to be long standing. Is there something new/different today as opposed to every other day when this problem has been present? Does this relate to a gradual worsening of the symptom itself? Has the patient developed a new perception of its relative importance (e.g. a friend told them they should get it checked out)? Do they have a specific agenda for the patient-provider encounter? Program Outcome #6: Show care that is effective, patient-centered, timely, efficient and equitable for the treatment of health problems and the promotion of wellness 14) You suggest to a patient that they should consider taking a drug to lessen the likelihood that they will experience an MI. The major side effect of the drug is that it can cause alopecia. Your patient strongly “resembles” the patients in the study in all ways. You attempt to assess how the patient “feels” about the risks and benefits of the treatment using a disutility scale (as shown below) and find that the patient assigns a disutility score of 0.8 for the alopecia and 0.2 for the MI? Taking these disutility scores into account, calculate the likelihood of being helped and harmed (LHH) assuming that the NNT is 16 and the NNH is 48. Show your work, but no source documentation is required! Disutility Scale (0 = Death and 1 = Full Health) The Severity (S) Value = DA / DO = 0.8/0.2 = 4 The S value tells us how many times worse the patient feels the MI is compared to the adverse reaction of alopecia, i.e. an MI is 4x worse than the alopecia. LHH = (1/NNT) * S / (1/NNH) = (1/16) * 4 / (1/48) = 12 Program Outcome #7: Display a high level of responsibility and sensitivity to a diverse patient population 15) When dealing with patients from a culture different from your own, which of the following would be LEAST appropriate to do? A)Consider asking the patient, “What did you hope to get from today’s visit?” B)Be aware that cultural or folk medical practices may be incorporated into a care plan (with or without your knowledge) and inquire about the use of such practices. C)Consider asking the patient, “What would typically be done for you in a clinic in your country? D)Support incorporation of cultural/folk practices if there exists good scientific evidence that to do so would be harmful to the patient. Program Outcome #8: Conform to high standards of ethical practice and to legal/regulatory requirements 16) Find and paste answers to the questions, “What is the role of a PA? What do PAs do?” Please provide URL of site you used to answer this question. Q. What is a Physician Assistant (PA)? A. Physician assistants are health care professionals licensed, or in the case of those employed by the federal government they are credentialed, to practice medicine with physician supervision. As part of their comprehensive responsibilities, PAs conduct physical exams, diagnose and treat illnesses, order and interpret tests, counsel on preventive health care, assist in surgery, and write prescriptions. Within the physician-PA relationship, physician assistants exercise autonomy in medical decision making and provide a broad range of diagnostic and therapeutic services. A PA's practice may also include education, research, and administrative services. http://www.aapa.org/geninfo1.html 17) Find and paste Indiana code IC25-27.5-4-4 below.
